Non-Rocket Space Launch and Flight
At present, rockets are used for launches and flights into space. They have been intensively developed since World War II when the German engineer F. Von Braun designed the first long distance rocket FAU-2. In the subsequent 60 years liquid and solid rockets reached the peak of their development. Their main shortcomings are (1) very high cost of space launching $20,000 â 50,000/kg; (2) large fuel consumption; (3) fuel storage problems because the oxidizer and fuel (for example; oxygen and hydrogen) require cryogenic temperatures, or they are poisonous substances (for example; nitric acid, N2O3).
In the past years the author and other scientists have published a series of new methods which promise to revolutionize space launching and flight. These include the cable accelerator, circle launcher and space keeper, space elevator transport system, space towers, kinetic towers, the gas-tube method, sling rotary method, asteroid employment, electromagnetic accelerator, tether system, Sun and magnetic sails, solar wind sail, radioisotope sail, electrostatic space sail, laser beam, kinetic anti-gravitator (repulsitor), EarthâMoon or EarthâMars non-rocket transport system, multi-reflective beam propulsion system, electrostatic levitation, etc.
There are new ideas in aviation which can be useful for flights in planet atmosphere. Some of these have the potential to decrease launch costs thousands of times, other allow the speed and direction of space apparatus to be changed without the spending of fuel.
The author summarizes some revolutionary methods for scientists, engineers, students, and the public. He seeks attention from the public, engineers, inventors, scientists for these innovations and he hopes the media, government and the large aerospace companies will increase research and development activity in these areas.
